R - HTML 中并排的 htmlwidgets

Question

>假设我有两个htmlwidget

# Load energy projection data
# Load energy projection data
library(networkD3)
URL <- paste0(
        "https://cdn.rawgit.com/christophergandrud/networkD3/",
        "master/JSONdata/energy.json")
Energy <- jsonlite::fromJSON(URL)
# Plot
sankeyNetwork(Links = Energy$links, Nodes = Energy$nodes, Source = "source",
             Target = "target", Value = "value", NodeID = "name",
             units = "TWh", fontSize = 12, nodeWidth = 30)

和

library(leaflet)
data(quakes)
# Show first 20 rows from the `quakes` dataset
leaflet(data = quakes[1:20,]) %>% addTiles() %>%
  addMarkers(~long, ~lat, popup = ~as.character(mag))

我想将它们并排放置在 html 页面中。我该怎么做？我可以使用 iframe 吗？其他？

Answer 1

有很多方法可以回答这个问题。 通常，大小和定位会根据htmlwidget的作者而有所不同，因此您可能需要进行一些实验。 如果您不打算将CSS框架与网格帮助程序一起使用，最简单的方法是将每个htmlwidget包装在tags$div()并使用CSS。 您可能还对RStudio http://github.com/rstudio/flexdashboard 中非常漂亮的基于flexbox的仪表板软件包感兴趣。

library(htmltools)
browsable(
  tagList(list(
    tags$div(
      style = 'width:50%;display:block;float:left;',
      sn
    ),
    tags$div(
      style = 'width:50%;display:block;float:left;',
      leaf
    )
  ))
